CONTAINER CAP.

Application led September' 23, 1922. Serial No. 590,155.

T0 all 107mm t may concemt.'

Be it known that I, EMMEN' I). RYBURG, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Container Caps, of which the following is a specification.

My invention relates to closures for containers and while it may be used for general purposes it is more particularly adapted for the filler openings of automobile radiators and gasoline tanks.

One important feature resides in the quick manner in which the device may be opened for the introduction into the Container of water, gasoline, or other liquid, and the rapid manner in which said device may be closed after such introduction, such opening and closing movements being` ac.- complished in much less time than is possible with the screw caps usually employed.

Another feature resides in the fact that there are no removable parts to become lost as in the case where removable screw caps are employed.

Other features will hereinafter appear and in order that the invention may be fully understood, reference will now be had to the accompanying drawings, in which:

Fig. 1 is a broken plan'view of one form of the device in closed position and applicable to the filler openings of automobile radiators.

Fig. 2 is a plan view of the device in open position.

Fig. 3 is a vertical cross section on line III-III of Fig. l.

Fig. l is a detail plan view of a segmental ylate. l Fig. 5 is a plan view of a form of the device applicable to the gasoline tank of an automobile, the device being` in closed position.

Fig. 6 is a plan view of the last-mentioned device in open position.

Fig. 7 is an irregular vertical cross section on line VII-VII of Fig'. 5.

Fig. 8 is a reduced plan View of an inner plate. n

Referring now more particularly to the form disclosed by Figs. 1 to 4L, inclusive, 2

designates a tubular member provided with threads 4 at its lower portionso that it may be screwed upon the neck of the filler opening of a container, such, for instance, as a radiator (not shown) in place of the usual screw cap. IVhile I have shown internal threads 4t it is to be understood that the tubular member 2 may be externally threaded should the neck of the filler opening` be internally threaded.

The upper portion of the tubular member 2 is provided with an integral plate 6 having an opening 8,- which is normally closed by a cap 10 rotatably mounted upon said plate 6. The cap l0 consists of a top plate 12 and a depending marginal flange 14, which latter snugly but rotatably embraces the upper peripheral portion of the tubular member 2 and assists in holding` said cap l0 in position. The plate 12 has an opening 16 adapted to register with the opening 8 when the cap l() is opened by rotatinga half revolution in the direction of arrow a Fig. 1, to the position disclosed by F 2. The rotary movement of the cap 10, to open and close the device, is limited by a stop 18 extending downwardly through the top plate 12 and into the path of the ends of the opening 8 in the plate 6.

2O designates a segmental plate which bears against the underside of the plate 6 and is connected to the top plate 12 of the cap 10 by means of the stop 18 and a tubular rivet 22, which latter extends through axial openings in the plates 6, 12 and 20, as more clearly shown by Fig. 3.

In some instances the rivet 22 may be solid but I prefer to make it tubular as shown and described, so that a motormeter or an ornamental device can be readily installed on the device. Before shipping the device from the factory the tubular rivet 22 is closed by a plug 24 removably held in place by a nut 26, so that said plug-24 may be readily removed in case a motormeter or an ornamental device is to be installed as above stated. The plug` 24 is provided with a removable bushing 28 to tit the stems of motormeters or other devices having stems too small to snugly tit the opening through the rivet 22.

The segmental plate 2O assists in holding the cap l() snugly upon the plate 6 of the tubular member 2 and also in preventing any dust which might work through the openings 8 and 16 when the cap 10 is closed, from' passing downwardly through said tubular member 2 and entering the container to which it is connected. The plate 6 has a circular groove 30 formed in the upper surface thereof, so that any dust entering between said plates 6 and l2 will pass into said groove 30 and thus in a manner form a gasket which will coact with the plate 2O in preventing dust trom pasing downwardly through the tubular member 2. V

For convenience in rotating the cap l() to open and close the device I provide said cap with oppositely-disposed handles 32, which may be of plain or ornamental design. In some instances the segmental plate 2O may be dispensed with, in which case the lower flange of thetubular rivet 22 would be made to engage the undersurface of the plate 6, but I prefer to employ said segmental plate 2O as it assists in holding the cap 10 upon the tubular member 2 and in excluding dust, as above set forth.

In order to prevent the device from being stolen when installed on the filler opening of a container, I provide the tubular member 2 with a threaded lateral opening 34 for the reception of a set screw 36, which may be screwed tightly against the neck of the -iiller opening to lock said tubular member 2 in place. The set screw 36 is shorter than the opening 34 as shown, so that when screwed against the neck of the hller opening as stated its outer end may be concealed Y by a suitable plug forced within the opening 34.

rllhe torni disclosed by Figs. 5 to S inclusive, is designed more particularly for use on the filler openings of gasoline tanks (not shown). Said form embodies a tubular member 2a having an upper plate 6"L providedwith an opening 8a. rIlhe lower portion rof the tubular member 2FL has threads 4a for engaging the threads of the liller opening of a gasoline tank in lieu of the screw cap usually employed for that purpose. Said tubular member 2 also has an internal tiange 4b adapted to engage the upper margin of the neck of the filler opening.

The opening 8a is normally closed by a cap 10a having a thumb piece 10b, which may be readily grasped with the thumb and ltoretinger preparatory to moving the cap l()a to open or closed position. The cap l()a is provided with a fixed pivot 22a, which has a round portion 40 journaled in the plate 6ZL and a rectangular portion 42 to fit into the corresponding opening 44 in a circular plate 46 against the underside of which the lower end of the pivot 2221 is upset to hold the cap 10 and the plate 46 together. The rectangu- Y lar'. Vportion 42 of the pivot V22n passing through the corresponding hole 44 in the plate 46, causes the latter to rotate vwith the cap 10a when the same is swung to open or closed position.

` The plate 46 is provided with an opening 48, which registers with the opening 8a when the opening VSa and the joint betweenV the closed. cap l0 and the topV 6a, vwhich joint however is sui'ticiently tight to practically exclude all dust. like the tubular member 2 may be secured -trom theft by means of a setl screw 36,

The operation of opening and closing the device is very simple. In order to open the device the member 10" is grasped and the cap l0 swung from the position disclosed by Fig. 5 to the position disclosed by Fig. 6, to uncover the opening 8a. As the plate 46 is caused to rotate with the cap l0 through the intermediacy of the pivot 22, the opening 48 is brought into coincidence with the opening 8, so that gasoline may be readily The tubular member 2 supplied to the container throughthe tubu- Y lar member 2a. The device is closed by moving thecap 10 to the position disclosed by Figs. 5 and 7, which movement causes the solid portion ot the plate 46 to pass beneath the opening 8 and thus coact with the cap 10;L in preventing the passage of dust through said opening 8a.

From the foregoing description it will be readily understood that I have provided devices embodying the advantages above pointed out, and while I have shown two 'forms of such devices I reserve the right to make such other forms as properly tall Y within the spirit and scope of the claims.

Having thus described my invention` what I claimV and desire to secure by ette-rs Patent, is: L V
